Background technique
Be mounted in the release bearing on the gearbox I outer shaft sleeve pipe from aligning pull type clutch release bearing unit.At work, the power transmission moment of torsion is big, and the axial separation force that rotating speed height, release bearing bear is bigger.Existing self-aligning pull type clutch release bearing adopts the two point form angle contacting, does not in use reach ideal effect, produces a series of early failure phenomenas.Mainly be that under the high temperature and high speed operating mode, lubricating grease runs off fast because of the axial bearing load poor-performing of release bearing, temperature sharply raises, and causes engineering plastics cage to lose efficacy.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of steel ball raceway groove sectional shape for oval at above-mentioned deficiency, can obviously improve the stressing conditions of steel ball and raceway groove, improved bearing capacity, trench edges can not produce under the effect of steel ball and peel off simultaneously, therefore designing elliptic channel and be the key parameter of angle contacting clutch shaft bearing structure sees in the formula, the outer fissure coefficient of curvature is that fe, interior raceway groove coefficient of curvature are fi, steel ball size d wrapping angle β, major axis a, minor axis b, the bearing axial carrying capacity is increased greatly, also can increase its radially bearing capacity.Its elliptic parameter is:
And having self lubricity preferably simultaneously, have greasy property 4 of elliptic channels good, that can bear bigger axial alternating force and the difficult inefficacy of retainer and contact from aligning pull type clutch release bearing unit the working life of having improved clutch release bearing.
Solution solution of the present utility model is: a kind of elliptic channel contact is from aligning pull type clutch release bearing unit, it comprises release sleeve and is positioned at bearing inner race on the periphery wall of release sleeve left side, there is bearing outer ring outside at bearing inner race, some steel balls distribute between bearing inner race and bearing outer ring, inwall at bearing outer ring, the outer wall of bearing inner race is provided for holding the raceway groove of steel ball, form shelves limit, a left side and right shelves limit in the raceway groove left and right sides of the inwall of bearing outer ring respectively, it is characterized in that: described bearing outer ring inwall, the raceway groove of bearing inner race outer wall is oval raceway groove; The oval raceway groove of bearing outer ring, bearing inner race is the oval raceway groove of arc greater than steel ball curvature and monosymmetric arc formation, forms four monosymmetric point of contact of oval raceway groove.
The oval raceway groove of bearing inner race described in the utility model technical solution bottom forms holds the grease arc, and the both sides of oval raceway groove are provided with back the fat chamfering; The oval raceway groove of bearing outer ring bottom forms holds grease arc groove, and the both sides of oval raceway groove are provided with back the fat chamfering.
The hem width that returns the fat chamfering described in the utility model technical solution is 0.6-0.8mm, is 0.2-0.5mm deeply, and angle is 25-30 °; The hem width that returns the fat chamfering is 0.6-0.8mm, is 0.2-0.5mm deeply, and angle is 25-30 °.
Be provided with the refractory metal retainer of locking ball between bearing inner race described in the utility model technical solution and the bearing outer ring.
The elliptic channel arc of the utility model bearing outer ring, inner ring forms two monosymmetric four point of contact greater than the elliptic channel of steel ball curvature and monosymmetric circular arc formation, two so just original point of contact formation four-point angle contacting with the bearing outer ring elliptic channel, thereby in working order, form lubricant film easily, have good lubricating property, can bear bigger axial alternating force simultaneously.The utility model is owing to hold grease in bearing outer ring, inner ring elliptic channel bottom, and the both sides of raceway groove are provided with back the fat chamfering, thereby more helps the formation of quick backflow of lubricating grease and lubricant film.The utility model is owing to be provided with the refractory metal retainer of locking ball between bearing inner race and the bearing outer ring, thereby can thoroughly solve the problem that engineering plastics cage lost efficacy.The utlity model has the characteristics that greasy property is good, can bear bigger axial alternating force and the difficult inefficacy of retainer.The utility model is mainly used in 4 contacts of elliptic channel on heavy goods vehicles, engineering truck, bus and passenger car, the commercial car from aligning pull type clutch release bearing unit.
